Assuming that metric type II radio bursts from the Sun are due to magnetohydrodynamic shocks driven by coronal mass ejections (CMEs), we estimate the average CME acceleration from its source region up to the position of ...

A brief review of the recent work done on Type-I radio emission in the Indian Institute of Astrophysics is presented. The most plausible low frequency turbulence needed to generate the type-I bursts is shown to be ion-sound ...
